!!

From Monday to Friday I think about weekends OR how I will spend Saturday and Sunday. I don’t have many friends, that’s why I have to come up with the entertaining ideas for me on my own. I’m not a couch potato and hate spending my time only beside the TV-set. I’m likely to go somewhere on foot just to have a walk if I have no other plans. Active life captivates me most of all.
On Saturday morning I never wake up too late. I’d rather wake me up at dawn than lie slugging in a bed till midday. After drinking a cup of coffee, I spend 15 minutes on reading the news about politics. As always they promise to give people high salary and pension but their words speak louder than actions and not the reverse. I don’t get upset, drink another cup of coffee and prepare for a journey to the movies.
Sometimes I change this plan and go to the exhibition if there’s one in my town. I love visiting operas, theaters and plays too, but last Saturday all tickets were reserved in advance. When I came up to a box-office, a ticket seller told me that it was late – no tickets left.
As a rule, my day off is always full of events. I never get bored and even if there’s no place where I might go to, I make an effort to do my best and spend this day productively. I read books or learn something, do sports and make plans for the next weekends.
